SPECIFICATION formingpart of Letters Eatent N o. 694,814dated March 4,1902.

Application led October 12, 1901.

To all whom, it may concern.- l

Beit known thatI, AUGUST Zwloknn, a citizen of the United States,residing at Rusk, in the county of Cherokee and State of Texas, haveinvented new and useful Improvements in Knives, of which the followingis a speciiication.

My invention relates to pruning-knives; and its primary object is toprovide a device of this character of simple and inexpensiveconstruction which will be light, but strong and durable and capable ofgeneral use as a pruning implement for shrubbery and trees.

The improvement may be used with orwithout a rod or pole and is providedwith means for suspending it from the clothing of the user whentemporarily not required for use.

The construction of the improvement will be fully described hereinafterin connection with the accompanying drawings, which'form part of thisspecification, and its novel features will be particularly pointed outin the appended claims.

In the drawings, Figure 1 is a View in perspective of the inventionapplied to a pole. Fig. 2 is a vertical section of the same. Fig. 3 isfront elevation of the knife with the pole ing the knife from the personof the user. Fig. is a side elevation of the securing-yoke employeddetached. Fig. 5 is a perspective view of the upper end of the pole.Fig. 6 is a horizontal section illustrating'the means for securing theknife-handle and yoke to the pole. Fig. 7 is a fragmentary sectionalView taken through one end of the handle and illustrating the relativepositions of the point of the knife and the guard-plate; and Fig. 8 is aside elevation of a knife, illustrating the means of fastening the saineVto a garment.

The referencen umeral 1 designates the hollow knife-handle, formed froma single piece of metal and having at'its front side'a slot 2, extendingthroughout the length of the handle. The upper ends 3 of the sides ofthe khandle are extended and bent inward upon themselves to formfriction-jaws 4, between which the blade 5 is pivotally secured by arivet 6. A shoulder 7 is formed at the upper end of the handle to serveas a stop against which theshoulder 8 of the blade abuts when the bladeis fully opened, as shown by dotted Serial No. 78,499. (No models iinesin Fig. 1. The blade 5 is of hook form, as shown, and its point 9 whenthe blade is closed rests upon a guard-plate l0, of suitable material,set into the handle, as shown in Fig. 7.

The knife comprising merely the handle and blade as thus far describedis a convenient implement for garden use; but when the device is to beemployed as a pruning-hook for trees the blade is turned to the positionshown in Fig. l and a pole 11 is inserted into the hollow handle,whichserves as a socket for the pole.` The upper end of the pole isformed Witha longitudinal slot 12 and a transverse opening 13 for thepurpose hereinafter explained.

14 designates a yoke fitting over the blade and having an arm 15, formedwith `a perforated lug 16 and a curved finger-piece 17. TheluglG-extends through the slot in the handle, and its perforationregisters with the opening 13 of the handle and diametrieally oppositeholes 18, formed in the handle. A colter-pin 19 extends through thehandle, pole, and lug 16,` thus securing these parts firmly together andmaintaining the blade in the position shown in Fig. l.

The utility of the device will be readily appreciated from the foregoingdescription, in connection with the illustration in the drawings.

The pole 1l may be of any desired length, and the ease with which thepole may be attached and det-ached constitu tes an important feature ofthe invention.

In Fig. 8 I have shown means for suspending the knife from the person ofthe user, which consists of a coil-spring 20, formed at its ends withinwardly-projecting pins 2l, adapted to engage the clothes of the user.The coils of the spring may be forced between the sides of the handle 1,and byresting within the slot 2 the knife will be retained in asupported position-that is, by confining the spring within the handlethe liability of the knife becoming misplaced or dropping will bereduced.

I claim- 1. A pruning-knife comprising a slotted handle and a pivotedblade, in combination with means for holding said blade in apartially-closed position, comprising a yoke fitting over the blade anda depending handle and means for detachably securing the said dependinghandle to the handle of the knife.

2. A pruning-knife comprising a hollow slotted handle having registeringopenings and a pivoted blade, in combination With a pole fitting Withinthe handle and having an opening registering with the openings in thehandle, a securing-pin extending through said openings, and means forsecuring the blade in partially-closed position.

3. A pruning-knife, comprising a hollowr slotted handle havingregistering openings and a pivoted blade, in combination with a polefitting Within the handle and having an opening registering with theopenings in the handle, a securing-pin extending through said openings,and means for securing the blade in partially-closed position comprisinga yoke fitting over the handle and having a perforated ear extendingthro'iigh the slot in the handle, and a slot in the pole and held by thepin which secures the pole to the handle. 4. The combination with apruning-knife comprising a slotted handle and pivoted blade, of asuspending device therefor consisting of a coil-spring having pinsprojecting from the ends thereof.

In testimony whereof I affix my signature in presence of two Witnesses.
